RAIL-0min. I

- Specification of Letters Patent. Patented Aug. 5 1 913.

Application filed May 17, 1913. Serial No. 768,316.

To all whom it may concern: Be it known that I, Tnoisms COLEMAN, a

subject of the King of England, residing at' Bridgeport, Cape Breton, in the Province of Nova Scotia and Dominion of Canada, have invented certain new and useful Improvements in Rail-Chairs, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in rail chairs, and an'objectthereof is the pro vision of a. device of this character in which novel means are provided for securing the rail to the tie.

Another object of this ivention is the provision of a rail chair comprising a tie plate, the plate having recesses formed therein on its opposite edges and near the opposite ends thereof, the rail being adapted to rest upon the plate between the recesses therein, and spikes driven into the tie through the recesses, the spikes being of such construction to engage under the plate to prevent accidental displacement of the spikes, owing to the jar of trains passing over the rails.

A still further object of this invention is the provision of a specially constructed,

spike, the spike having an upwardly projeeting head on one face thereof 'which is adapted to engage over the base flange of the rail, and the spike being enlarge-d on one side thereof to form an upwardly facing shoulder, the shoulder of, the spike being adapted to engage the under face of the tie plate to prevent accidental disengagement of the spike from the flange of the rail.

lVith these and other objects in view, my

.invention consists in certain novel construc tions, combinations and arrangements of parts, to be hereinafter more fully described, claimed and illustrated in the-accompany ing drawing, in which Figure 1 is a. side elevation of the chair showing the rails connected thereto; Fig. 2

is atop plan view partly in section showing the chair connected to one of the rails; and

Fig. 3 is a transverse section showing one of the rails connected to the chair.

Referring more particularly to the drawing, the letter A designates a tie, B my improved rail chair, C a rail, D a connecting v v bar or binder for the rails of the track, and

E my improved spike for securing the rail and chair to the tie. The joint chair comprises a rectangular tie or base plate 5 which is adapted to extend longitudinally .of the tie and is provided in its opposite e ges near the opposite ends of the rail with recesses 6. The plate is provided on its outer end with a reduced extension 8, the purpose of" which will be. hereinafter morejfully described. The joint chair is placed upon the tie so that the plate 5 extends slightly out of longitudinal alinement thereof, and the rail is then placed upon the plate so that therecesses 6 are disposed upon oppositesides of the rail adjacent the base. flanges thereof. Each of the spikes comprises ashank 9 which is formed with a head 10 and projecting from the forward face of the head is a' flange or lip 11. One side of the spike is enlarged and beveled for a portion of its lengtlnas at 12-, the enlarged portion there of terminatingin an upwardly facing shoulder 13 which is spaced a suitable distance from the head 10 of the spike. \Vhen the rail is seated upon the plate, the spikes E are driven into the tie through the recesses (3, so that the flanges 11 thereof extend inwardly of the plate'to bear-against the'base flanges of the rail.- .VVhen the spikes have been driven into the tie so that the flanges 11 rest upon the base flanges'of the rail, the shoulders 13 are arranged below the lower face ofthe plate 5, and when the plate is tapped into longitudinal alineinent with the tie, the inner walls of the recesses (3 will be moved over the shoulders 13 to keep the spikes in position in the tie.

The binder B which comprises a lOllglttP dinal bar 14: which is provided on its opposite ends '\vith inner and outer ofiset flanges 15 and 16 respectively is then placed between the rails, the offset portion of the binder being provided with an opening 17. The binder is placed so that the offset portions 15 engage over the longitudinal edge of the plate 5 so that the opening 17in the binder registerswith the opening 7 in the plate, and the flanges 16 engage over the opposing base, flanges of the rail. \Vhen the several parts are in this position, .the'

usual track spikes 18 are driven into the tie through the registering openings 7 andv 17' whereby the rails are securely bound together.

To suitabl brace the rails against thrust of the whee s, the reduced extension 8 of the late 5 is inclined inwardly and ob-.

lique y, so that the extremity of the exten- 1 10 from the tie is eliminated. By the provision the rail when heavy thrust is imposed therehp'on. It will of course be understood that the plate 5 may be used without the extension 8 being formed'therein, but it is preferable to use the bracing extension as a very solid track is provided thereby.

From the above description taken in con-; nection with the accompanying drawing it will be seen that I have provided a joint chair which may be quickly and easily secured to the tie, and one in which all danger of the accidental disengagement of thespikes of-shoulders 13 on the spikes which engage under the under face of the tie plate, it will be seen that the entire weight of the train passing over the rails is brought to bear upon the spikes as wellas upon the rails, so that the spikes are securely held in engagement with the tie.

Having thus fully described my invention what Idesire to claim and secure by Letters Patent is:

1. A rail chair comprising a tie plate, said plate being formed with recesses in itsopposite edges adjacent its opposite ends, a rail seated upon said tie plate between said recesses, spikes adapted to be-driven into the tie through said recesses, said spikes adapted to engage the base flanges of said rail,

and said spikes being also formed with means to engage under the walls of said recesses as and for the purpose described.

2. In a rail chair comprising a tie plate having recessesin its opposite edges adjacent its opposite ends, the combination'with a rail seated upon said plate between said recesses, and spikes adapted to be driven into said tie through said recesses, the spikes being formed with flanges to engage over the base flanges of said rail, and said spikes being also formed with shoulders adjacent their upper ends to engage under the walls of said recesses in said tie plate, as and for ;the purpose described.

3. A rail chair comprising a tie plate having recesses in its opposite edges adjacent its opposite ends', in combination with a rail seatedupon said plate between said recesses, and spikes adapted to be driven into said tie between the sidewalls of said recesses, said spikes being formed with flanges to engage over the base flanges of said rail, the innei faces of said spikes being formed with shoulders adjacent their upper 'ends to engage under the inner walls of said recesses in the tie-plate,:as and for, the purpose described In testimony whereot I hereunto afiix my signature in the presence of two witnesses.
